Invitae RCV000812324 SCV000952635 uncertain significance Pierson syndrome; LAMB2-related infantile-onset nephrotic syndrome 2022-03-23 criteria provided, single submitter clinical testing This variant is present in population databases (no rsID available, gnomAD 0.0009%). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 656020). This variant has not been reported in the literature in individuals affected with LAMB2-related conditions. This sequence change replaces isoleucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 687 of the LAMB2 protein (p.Ile687Met).
